Megan Mullally joined her
"Children's Hospital" co-stars to speak with reporters before their Comic-Con panel on Friday (July 22) afternoon, and the actress told
Zap2it that we could be seeing her on
"Happy Endings" when the show returns to ABC this fall.

"I'm going to do a little arc," she says. "I think it's an arc."

Be still our hearts. So what can we expect to see from the comedian when she stops by one of our favorite show's of the last season?

"I haven't signed any paperwork yet," she admits, "but rumor has it I'm going to be playing
Casey [Wilson's] mother. I love her."

A show representative couldn't immediately confirm that they're speaking with the actress, but Mullally seems positive. "I think they do really funny stuff," she says of the sleeper hit. "They have a really cute cast."

"Wow, that was mind-blowing," she says. "His PR firm, each day, sends him anything that's written about him, and there were like 30 blogs about it. I've never seen anything like that. People online went insane."

Offerman took it much better than the fans.

"Nick is a great man, and he took it like a champ," she says, "but we did remark on the sheer volume that was written. It was pretty incredible. It's flattering."
